Tie down



FIG. 1 is a top plan view of the tie down;

FIG. 2 is a front elevational view;

FIG. 3 is a left side elevational view;

FIG. 4 is a rear elevational view;

FIG. 5 is a right side elevational view; and,

FIG. 6 is a perspective view.

Thus broken lies appearing in the drawing figures are for illustrative purposes only and form no part of the disclosed ornamental design.

A bottom plan view is not shown as it forms no part of the claimed ornamental design. 

I claim the ornamental design for a tie down, as shown and described.
